For the treatment of VWD

Types of von Willebrand Disease (VWD)

There are three main types of von Willebrand disease (VWD): type 1, type 2, and type 3.1 It is important to know which type of VWD a person has because generally, bleeding worsens from type 1 to type 3. However, bleeding can be mild, moderate, or severe within each type. Treatment may also depend on the type of VWD.

Type 1 von Willebrand Disease2,3

  • Most common and mildest type (60-80% of patients)4
  • von Willebrand factor (VWF) works normally but there is not enough of it
  • Symptoms are usually mild, but it is possible to have serious bleeding

Type 2 von Willebrand Disease

  • Affects approximately 10-30% of patients4
  • There are different subtypes of Type 2 VWD depending on the type of VWF defect (2A, 2B, 2M, and 2N)
  • Symptoms are usually moderate, but serious bleeding is possible

Type 3 von Willebrand Disease

  • Rarest type. Affects approximately 1-5% of patients4
  • Very little or no VWF is present. Low levels of FVIII
  • Most serious. Symptoms are usually more severe. It is possible for people with Type 3 to have more serious bleeding issues, such as bleeding into muscles or joints, sometimes without an injury

Indications and Usage

wilate® is a von Willebrand Factor/Coagulation Factor VIII Complex (Human) indicated in children and adults with von Willebrand disease for on-demand treatment and control of bleeding episodes, and for perioperative management of bleeding. wilate® is not indicated for the treatment of hemophilia A.

Important Safety Information

wilate® is contraindicated for patients who have known anaphylactic or severe systemic reaction to plasma-derived products, any ingredient in the formulation, or components of the container.

Hypersensitivity or allergic reactions have been observed upon use of wilate® and may in some cases progress to severe anaphylaxis (including shock) with or without fever.

When using a factor VIII (FVIII)-containing von Willebrand Factor (VWF) product, the treating physician should be aware that continued treatment may cause excessive rise in FVIII activity. Monitor plasma levels of VWF:RCo and FVIII activities in patients receiving wilate® to avoid sustained excessive VWF and FVIII activity levels, which may increase the risk of thrombotic events.

Patients with VWD, especially type 3 patients, may potentially develop neutralizing antibodies (inhibitors) to VWF, manifesting as an inadequate clinical response. Since inhibitor antibodies may occur concomitantly with anaphylactic reactions, patients experiencing an anaphylactic reaction should also be evaluated for the presence of inhibitors.

wilate® is made from human plasma. As with all plasma-derived products, the risk of transmission of infectious agents, eg, viruses and, theoretically, the variant Creutzfeldt-Jakob disease (vCJD) agent or other unknown infectious agents, cannot be completely eliminated. Despite measures to reduce this risk, such products may still potentially transmit disease.

The most common adverse reactions to treatment with wilate® in patients with VWD have been urticaria and dizziness. The most serious adverse reactions to treatment with wilate® in patients with VWD have been hypersensitivity reactions.
